DC Parasitic losses (Which can be removed totally with a properly wired battery cut off, or removing battery cable (negative (-) if I was so inclined), which I cannot advise because, if you forget to switch on or reconnect cable: the breakaway safety switch is disabled, the CO/LP detector disabled and the slide controller unpowered, which as I understand, but didn't prove, could cause the slide to not stay in.
I'm going by the TM-2030 which is not perfect, but is considered very reliable; it is optioned to read watts so I didn't have to do the math. It is reading current flow across an instrument grade 500A/50mV shunt, via kelvin connections; and is the only path from the battery bank's negative to ground. The meter does bounce. So, I am showing the settled down, highest reading.
Solar and Inverter been off... staying off.
1) Pulled all fuses from the WFCO DC distribution panel
2) Disconnected everything from the battery except the TM-2030 = 3.65W shown (that is the meter's own impedance)
3) Connect breakaway still 3.65W
4) Connect slide only reading = 4.15W showing
5) Connect feed to audio amp still 4.15W
5) Connect WFCO DC panel = 6.67W indicated
(note- 3 red "blown fuse" indicators lit which represents a very small load)
6) Bedroom, with Maxxair and CO and LP detector = 6.17W showing (1 indicator off)
7) Bathroom, with the other Maxxair and the basic radio = 6.17W (second indicator off)
8) Third fuse turned off third indicator still 6.17W
9) All fuses in still 6.17W
1) The TM-2030 draws 3.65W
2) The slide controller - .5W
3) The WFCO panel with the CO/LP detector at 2.02W
Note: it doesn't matter to me if the panel itself uses power, or how much the detector uses by itself, they both have to be there and they play well together.
4) No other DC device that I have (to be clear): radio, maxxair fans, happijack, etc., etc. is drawing any DC watts.
The total parasitic loss not considering the TM-2030 with nothing turned on is 2.52W or
.2A (less than 1/4A) With the TM-2030 for those with one, it is 6.17W or less than 1/2 amp.
Note too FlyBob, the water pump isn't showing any current draw when off. I suppose the reading was bouncing or I didn't let it settle down.
